Does taking EC during my period mess up my cycle?

This Article

I had unprotected sex during the first day of my monthly period. I took EC right after. And I noticed that my period got very light to the point it's barely there already. Is this because of the EC? When can I expect my next period since my period for this month was interrupted by the EC?

Yes it is possible that the emergency contraceptive caused a change in your period. One of its side effects is a change in period but unfortunately, I can't tell you when to expect your next period. It is possible that you may see it again later this month or not see it again until next month-- it is very unpredictable.
